Definitions
- the present invention relates to fabric bleaching compositions comprising a peroxygen compound and, as bleach activator, a manganese complex.
- Bleaching compositions which contain a peroxide bleaching agent are well known.
- the bleaching agent functions to remove common domestic stains such as tea, coffee, fruit and wine stains from the soiled clothing at the boil. If the washing temperature is reduced to below 60° C., however, the efficacy of the bleaching agent is correspondingly reduced.
- a manganese complex for use as a bleach catalyst for a peroxy compound, which is a water-soluble complex of manganese II, III or IV, or mixtures thereof, with a ligand which is a non-carboxylate polyhydroxy compound, having at least three consecutive C--OH groups in its molecular structure, preferably sorbitol.
- certain other manganese complexes are excellent bleach catalysts for peroxy compounds and, relative to known bleach catalysts, provide enhanced bleach effects at low wash temperatures (e.g. at 15 to 40° C.) and/or using shorter washing times.
- the present invention provides a fabric bleaching composition
- a fabric bleaching composition comprising

- R 1 , R 2 , R 3 and R 4 are cycloalkyl, this may also be substituted, e.g. by C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy.
- R 1 , R 2 , R 3 , R 4 and X are optionally substituted aryl, they are preferably a phenyl or naphthyl group which may be substituted by C 1 -C 4 -alkyl, e.g.
- Y is alkylene, it is preferably a C 2 -C 4 -alkylene residue, especially a --CH 2 -CH 2 - bridge.
- Y may also be a C 2 -C 8 -alkylene residue which is interrupted by oxygen or, especially, by nitrogen, in particular the --(CH 2 ) 3 -NH--(CH 2 ) 3 -, --(CH 2 ) 2 -NH--(CH 2 ) 2 or --(CH 2 ) 2 -N(CH 3 )--(CH 2 ) 2 - bridge.
- Anions A include halide, especially chloride, chlorate, sulphate, nitrate, hydroxy, methoxy, BF 4 , PF 6 , carboxylate, especially acetate, triflate or tosylate.
- each R 1 is hydrogen

Abstract
A fabric bleaching composition comprising a peroxy compound and a specified manganese complex is disclosed, as well as a process for bleaching and/or cleaning a fabric by contacting it with said fabric bleaching composition.
Description
This application is a continuation of application Ser. No. 08/503,751, filed on Jul. 18, 1995 now abandoned.
The present invention relates to fabric bleaching compositions comprising a peroxygen compound and, as bleach activator, a manganese complex.
Bleaching compositions which contain a peroxide bleaching agent are well known. In such compositions, the bleaching agent functions to remove common domestic stains such as tea, coffee, fruit and wine stains from the soiled clothing at the boil. If the washing temperature is reduced to below 60° C., however, the efficacy of the bleaching agent is correspondingly reduced.
It is also well known that certain heavy metal ions, or complexes thereof, function to catalyse the decomposition of hydrogen peroxide, or of compounds which can liberate hydrogen peroxide, in order to render the peroxide compound effective at temperatures below 60° C.
For example, in U.S. Pat. No. 5,114,611, there is described the activation of a peroxy compound by a complex of a transition metal (Mn, Co, Fe or Cu) with a non-(macro) cyclic ligand, preferably 2,2-bispyridylamine or 2,2-bispyridylmethane.
Moreover, in U.S. Pat. No. 5,114,606, there is described a manganese complex, for use as a bleach catalyst for a peroxy compound, which is a water-soluble complex of manganese II, III or IV, or mixtures thereof, with a ligand which is a non-carboxylate polyhydroxy compound, having at least three consecutive C--OH groups in its molecular structure, preferably sorbitol.
Other disclosures, relating to the use of metal complexes as activators for peroxy compounds in bleaches or detergents, include U.S. Pat. No. 5,227,084, U.S. Pat. No. 5,194,416, U.S. Pat. No. 4,728,455, U.S. Pat. No. 4,478,733, U.S. Pat. No. 4,430,243, EP-A-549 271, EP-A-549 272, EP-A-544 519, EP-A-544 490, EP-A-544 440, EP-A-509 787, EP-A-458 397 and EP-A-458 398.
It has now been found, surprisingly, that certain other manganese complexes are excellent bleach catalysts for peroxy compounds and, relative to known bleach catalysts, provide enhanced bleach effects at low wash temperatures (e.g. at 15 to 40° C.) and/or using shorter washing times.

A standard (ECE) washing powder is made up from the following components in the indicated proportions:
8.0% Sodium (C11.5)alkylbenzenesulphonate;
2.9% Tallow-alcohol-tetradecane-ethyleneglycolether (14 moles EO);
3.5% Sodium soap;
43.8% Sodium triphosphate;
7.5% Sodium silicate;
1.9% Magnesium silicate;
1.2% Carboxymethylcellulose;
0.2% EDTA;
21.2% Sodium sulphate; and
9.8% Water.
An aqueous wash liquid is then made up and contains 7.5 g/l of the ECE powder, 1.13 g/l of sodium perborate monohydrate and 0.015 g/l of the compound of formula (111) as described in Example 8.
Into 400 ml of the aqueous wash liquid (made up using town water of 12 degrees of hardness), there are placed 12.5 g. of test cotton fabric soiled with red wine, tea, coffee or blackberry stains, as well 37.5 g. of bleached cotton (i.e. giving a liquor ratio of 1:8).
The respective wash baths are each heated from 15° C. to the test temperature of 25° C., 40° C. or 60° C. over a period of 10 minutes; and held at the respective test temperature for a further 10 minutes. The respective swatches are then rinsed under flowing, cold town water, spun dry and ironed.
The brightness value (Y) of the respective test swatches is then determined using an ICS SF 500 spectrophotometer. The value Y provides a measure of the level of bleach effect achieved. A difference of 1 Y unit is clearly detectable visually.
For reference purposes, the respective Y values are determined for each of the washed goods at 25° C. using perborate alone (i.e. using no compound of formula 109).
The results obtained are set out in the following Table.
